CVE-2026-54085
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
Wazuh versions 4.2.0 through 4.14.6 have multiple active response scripts that pass attacker-influenced alert fields to privileged system commands without validating their format, allowing argument injection into tools running as root.
Risk Assessment
An attacker can inject arguments into commands such as pfctl, npfctl, ipfw, route, netsh, and passwd, potentially leading to system compromise or account lockout. This could result in full host compromise.
Recommendation
Upgrade Wazuh to version 4.14.7. Restrict log event sources and monitor active responses for anomalous field values.
Original NVD description (English source)
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.2.0 through 4.14.6, multiple active response scripts pass attacker-influenced alert fields to privileged system commands without validating their format, allowing argument injection into tools that run as root. Five of the eight scripts that handle the srcip field, route-null.c, netsh.c, pf.c, npf.c, and ipfw.c, omit the get_ip_version() check that rejects non-IP input, and disable-account.c passes the dstuser field to passwd/chuser with only a comparison against "root". An attacker who can inject crafted log events, for example via syslog, can supply srcip or dstuser values that, when an active response rule triggers, are passed unvalidated to firewall and account-management commands such as pfctl, npfctl, ipfw, route, netsh, and passwd. This enables injecting additional command arguments, and on Windows the unquoted CreateProcess command-line concatenation in wpopenv() lets a srcip containing spaces add further arguments, while disable-account.c can be abused to lock arbitrary system accounts. This issue is fixed in version 4.14.7.
